CHAIN OR RING MANUFACTURE.

Specification of Letters Patent.

Patented Jan. 18, 1916.

Application filed April 29, 1913. Serial No. 764,338.

T 0 all whom it may concern Be it known that I, KUNO PEISELER, a subjectof the Emperor of Germany, and a resident of F rankfort-on-the-Main, inthe Empire f Germany, have invented certain new and useful Improvementsin Chain or Ring Manufacture, of which the following is a specification.

This invention relates to a new form of endless ring or link,particularly the links of a chain.

The main object of the invention is to cheapen the cost of production ofchains by increasing the speed at which the individual links can beWelded and at the same time maintain an efficient, neat-appearing chain.

It is a further object to produce a chain whichcan be made on a verysimple and cheap welding apparatus and an apparatus that can be, handledby an unskilled operator, thus further reducing the cost.

Heretofore chains have been made up of links, the ends of which areeither buttwelded or lap-welded, the electric welding process beingutilized for purposes of speed, economy and efliciency. In buttweldingit is necessary to have special forms of. holders and upsetting devicesand the heating period is necessarily long, thus making. the machinebothexpensive to build and expensive to operate. In the lap-weldingprocess-it is necessary to first shape the ends of the link (as for ascarf weld) and then provide a nicety of adj ustmentto" bring theendsproperly one over the other. Also a considerable amount of currentis necessary as quite an area of metal is in contact.

By this invention, the necessity of specially preparing the ends of theblank as in lap-welding is obviated and the utilization of a largeconsumption of current as in buttwelding is avoided.

To these ends the invention consists in the improved article hereinaftermore particularly described and then specified in the c aim.

In the accompanying drawings, Figure 1 IS an end elevation of a chainlink assembled in accordance with this invention. Fig.

2 is a side elevation of the same. F ig.- 3.is a plan view of the link.Fig. 4 is a plan view of a chain made in accordance with this invention,the individual links being passed from one wire to the other andpressure applied to the heated section afforded by the passage of thecurrent, all as well understood in the electric metal working art. Aswill be readily understood by those skilled in the art, the restrictedarea of contact at the crossing point will allow the metal to quicklyreach the welding heat and a quick, positive weld is efi'ected on theapplication of the necessary pressure, applied transverse to the link 1.

In Fig. 4 is illustrated a section of a chain composed of links whichare twisted, the links per se being formed in thesame manner as beforedescribed.

It will be understood that rings or other continuous closed bodies ofwire may be formedin the same wayas the chain links described and thatthe invention is applicable thereto.

What I claim as my invention, is:

A chain link composed of a single length of wire formed into a singleloop having its ends crossing one over the other and electricallyWeldedtogether at the inter secting point.
